Ion channels in erythrocytes: A novel understanding from regulation of erythropoiesis and physiological function to diagnostic measures and therapeutic concepts

Project description

Innovative treatment of red blood cell disorders

Erythrocytes (red blood cells) make up approximately 84 % of all human cells and rely on ion channels to respond to various stimuli during circulation. While these channels are essential for erythrocyte function, their specific mechanisms and regulation, including ‘pseudo-action potentials,’ remain poorly understood. Supported by the Marie Skłodowska-Curie Actions programme, the INNOVATION project aims to advance knowledge of ion channel functions to improve treatments for red blood cell disorders. The project will analyse erythrocyte functionality using patient samples linked to channelopathies. The project will also address key obstacles such as genetic manipulation of progenitor cells, erythrocyte differentiation, and the need for robust electrophysiological recordings. Additionally, the project will provide training in transferable skills for 10 doctoral candidates.

Objective

Erythrocytes represent an estimated 84% of all cells in the human body. During circulation, they experience a huge variety of physical and chemical stimulations, such as pressure, shear stress, hormones or osmolarity changes. These signals are translated into cellular responses through ion channels that modulate erythrocyte function. Ion channels in erythrocytes have only recently been recognised as the utmost important players in physiology and pathophysiology. Despite this awareness, their signalling, interactions and concerted regulation, such as the generation and effects of 'pseudo action potentials', remain elusive. INNOVATION proposes a systematic, conjoined approach using molecular biology, in vitro erythropoiesis, state-of-the-art electrophysiological techniques, methods to detect erythrocyte functionality and patient samples (channelopathies and other red blood cell-related diseases) to decipher and make use of ion channel functions in terms of disease treatment concepts. We need to overcome the challenges that hinder the gain of knowledge within the field, using genetic manipulation of progenitors, cell differentiation into erythrocytes, statistically efficient electrophysiological recordings of ion channel activity that are limited by the heterogeneity of the cell population (120 days of lifespan without any protein renewal) or access to large cohorts of patients.
Our multidisciplinary team includes biophysicists and cell biologists to investigate erythrocyte characteristics and bioengineers to develop diagnostic devices. INNOVATION involves academic research centres as well as diagnostic labs providing patient samples, blood bank research centres developing cultured transfusion products and SMEs that provide and develop diagnostic tools or innovative therapeutic red blood cell products. The consortium offers on-site training, secondments and a variety of courses in transferrable and complementary skills to 10 doctoral candidates.
